    The Molecular Mechanisms of Alzheimer’s

    Late-onset sporadic Alzheimer's disease accounts for about 99 percent of all cases, and is linked to multiple factors and pathogenetic mechanisms. One important contributor is a protein post-translational modification, known as O-linked β-N-acetylglucosamine, or O-GlcNAc. A recent paper in the Journal of Pathology reports on a new integrated proteomic pipeline that promises to harness advances in proteomics in ways that will ease investigations into hard-to-analyze O-GlcNAc.

    Networking Science to Improve Soil Organic Matter Management Opportunities

    Soil organic matter (SOC) is one of the largest actively cycling carbon (C) reservoirs, and direct human activities impact over 75 percent of C stocks in the upper meter of soil. Members of the International Soil Carbon Network provide a perspective, published Oct. 5 in Global Change Biology, on improvements that could help quantify potential losses of SOC or its sequestration.

    Enhanced Protein Analysis Could Help Early Disease Detection

    A paper by researchers at PNNL describes a new way to prepare and analyze blood samples that significantly improves researchers' ability to detect proteins that exist in very low concentrations.

About The Division

Scientists within the Biological Sciences Division perform biological systems science research and develop technologies focused on how cells, cell communities, and organisms sense and respond to their environment. Our vision is to measure, predict, design, and control multi-cellular biological systems and bio-inspired solutions for energy, environment, and health.

Our investigator-initiated and multi-institutional collaborative research, unique scientific instrumentation, and national program leadership translate the latest scientific discoveries into technologies that are beneficial to the nation.

Our research has applications to energy, environment, and human health missions of the U.S. Department of Energy (DOE), the National Institutes of Health (NIH), and other federal agencies.
